1 I ATTORNEY Patented Apr. 1, 1930 PATENT OFFICE ALFRED D. SUND, OF SANTA ROSA, CALIFORNIA BUMPER LEG FORBROOMS Application filed February 24, 1928. Serial No. 256,557.

The invention forming the subje'ct matter of this application relates to bumper legs for brooms, and particularly for the type of brooms generally used for street sweeping, and for all kinds of floors where this type of broom is used. I I In the present practice, the brooms used for street and floor sweeping are of the type shown in the drawing, and they are'very 40 rapidly covered with dust and refuse from the street or the floor. The brooms must be frequently cleaned from the dirt and dust acp broom upside down and bump the bristleholding member against the sidewalk or the floor. It is evident that while part of the dirt or dust is thus shaken out of the broom, the major part of it is shaken in'toward the I root of the bristles. At the same time the directbumping or hitting of the wooden part of the broom against the sidewalk or floor materially deteriorates the handle and the bristle-holding member.

- The primary object of the'invention is to provide a bumper leg which may be attached to' the handle of a broom in such a relation that the dirt may be shaken out of the bristles of the broom by repeatedly bumping the leg against the floor while the bristles of the broom are pointed toward the floor.

Another object ofthe invention is the provision of a bumper leg for brooms which may be readily attached to any size of broom han-,

, 40 die, and the length of which may be readily adjusted in accordance with the length of the bristles on the broom.

A still further object of the invention is to provide a bumper leg for brooms, the end 'of which carries a bumper made of rubber or other resilient material, whereby, when the broom is lowered upon a hard surface, such as the floor, the rubber bumper will cause the bumper and broom to bounce repeatedly on the fioor,thereby efiecting a vibration and shaking of the bristles of the broom.

Another: object of this invention is to provide a bumper leg for brooms which is highly useful and simple in construction. Conven ence of a :rangement, lightness, and comparative'inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention.

With the foregoing and other objects in View, my invention resides in the combination and arrangement of parts, and in the details of construction, hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention, hereinafter disclosed, may be made within the scope of the appended claims without departing from the spirit of the invention.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a streetsweeping broom, showing the same in a sweeping position, and showing my bumper leg attached thereto;

Figure 2 shows the broom in a position when the bumper leg thereon is in contact with the floor, in which position the dirt is shaken out of the bristles of the broom;

Figure 3 is a side elevation of my device, showing the same attached to the handle of a broom; and V Figure 4 is a rear elevation of the device, showing the handle of the broom in cross section.

Referring to the accompanying drawings wherein similar reference characters designate similar parts thruout, the Various figures described above adequately illustrate my invention, and the following detailed description is commensurate with the above mentioned drawings inrenabling an artisan to construct and assemble the constituent parts of the same.

In carrying out my invention, 1 make use of a broom of the type shown in the drawing and denoted in its entirety the numeral 5. Said broom comprises a handle 6, a bristlecarrying member 7, and bristles 10.

Ordinarily, when it is necessary to clean the bristles 8, the broom 5 is turned around so that the bristle-carrying member 7 may be brought repeatedly into contact with the ground, thereby causing the bristles 8 to vibrate andloosen the dirt therebetween. The inefiiciency of this method is self evident. A

more efficient method for shaking the bristles is effected by the use of the bumper leg de noted in its entirety by the numeral 8.

The bumper leg8 comprises a bracketmember 9 having asemi-circular portion 11 thereon. A' clamp 12 is disposed opposite the semi-circular member 11, the lower end of the clamp 12 being provided with a reduced neck 13, slidablein a slot '14, which slot is centrally disposed. in the bracketmember 9. On the free ends of the bracketmember 9 and the clamp 12 are oppositely disposed'lugs 16, provided with apertures therethru in which a screw 17 is received. In order to secure the bracket 9 to the handle 6 of the broom, the semi-circular portion 11 and the clamps 12 are placed around the handle 6. Then the clamp and the bracket are moved on the handle 6 intothe position desired. Then by tightening up a nut 18 on the screw 17, the lugs 16 are forced toward each other, thereby bringing the clamp 12 and the circular portion 11 into close contact with the handle 6. The inner surface of the portion 11 and the clamp 12 is corrugated as at 19, so that the corrugations pressed into the handle 6, securely hold the bracket .9 in place. When the lugs 16 are pulled toward each other, the opposite end of the clamp 12 is held in the slot 14 by means of an enlarged head 20 thereon engaging the face of the bracket 19.

A socket 21 is adjustably secured to the other end of the bracket 9 by means of a plate 22 extending from the socket 21 and having holes 23 therein. The bracket 9 terminates in a pin 24- bent so as to'extend at approximately right angles to said bracket.

4 The pin 24 may be brought into engagement with any one of the holes 23 in the plate 22. After the pin is brought into engagement with one of the holes 23, the plate 22 is fixedly secured to the bracket 9 by means of a bolt 26 and a nut 27 thereon, said bolt extending thru a hole 23 adjacent to the end of the plate 22 and in alignment with one of the two holes 28, which latter holes are disposed in the bracket 9.

A rubber bumper 29 is fixedly secured in the socket 21 by means of a transversely disposed pin 31. After the relative position of the plate 22 and the bracket 9 is adjusted so as to provide the desired length for the bumper leg, the leg is secured to the handle 6 of the broom 5 in the manner heretofore described. right angles to the handle 6.

The shaking out of the dirt accumulated in the bristles 10 is accomplished by bringing the handle 6 into a position where it is approximately parallel with the ground. broom is supported at the end thereof on the rubber bumper 29. As it is shown in Figure 2, in this position, the bristles 10 are pointed towardthe ground. By raising the leg olf the ground and dropping the same again, the rubber bumper 29 will cause the leg 8 and the end of the broom to bounce off the ground and drop again repeatedly, thereing of unitary character, the devicerequires no careful setting up, and lendsitself to effective application by the labor ordinarily available. 7

Having thus described my invention, what I new claim as novel and desire to secure by 7 Letters Patent is 1. In a bumperleg' for a broom handle, a bracket, adjustable means on thebracket for securing the same to the broom handle; and adjustable means for securing a bumperto the free end of said bracket.

2. In a bumper leg for a broom handle a bracket, means on the bracket fordetachably securing the same to said broom handle; an arm adjustably secured to said bracket; a socket on said arm; and a rubber bumper in said socket. I I

3. In a bumper leg adapted to be, secured to a broom handle; a bracket having a bear: ing portion thereon, a clamp member comp le' mentary to said bearing portion, means to detachably secure said bearing portion and said clamp member upon the broom handle, a socket, a hard rubber bumper therein; an arm on said socket having spaced apertures therein; a pin at the end of said bracket adapted to selectively engage one of said apertures, said bracket having holes therein sojspaced from said pin as to be in registry with one of said apertures when the pin is in engagement with said arm; and means extending through said hole and said registering aperture for securin said arm and bracket together.

n device of the character described comprising a dependent leg attachable at one of Thus the V its ends to the handle of a broom and having a socket formed in the other of its ends and a bumper Within the socket.

5. A device of the character described comprising a bracket, means for securing one end of the bracket to a broom handle, a bumper carried by the other end of the bracket and means for'adjusting the bumper longitudinally of the bracket.

In testimony whereof I affix my signature.
